Kiln Training Part 2 Glaze Kiln

If you damage a piece or damage the glaze, don’t fire it.

It is worse to fire a piece with damaged glaze, it can be fixed before firing but not after, leave a note

cleaning and washing shelves

Damaged kiln wash is best repaired on bisque firing
Ideally applied a day ahead
Check the kiln bottom, shelves, and coils for debris and vacuum it out, any little bit can damage the kiln

Be careful during loading

Again, be careful, glaze ware is
Check bottoms for glaze drips and be nice, wipe them off.
In general fire “as found” in terms of orientation but think about how things will “droop”

Firing Temps

Cone 6
Slow
15min hold
Preheat optional

Turn fans on

Super important
Evens out kiln
Metal vapor is produced depending on glaze, ex chrome or manganese are the big culprits, zinc too. Other gasses include co2, co, and h20

Don't open until it reaches 200F

Fill out the log!!!!

Ramp Hold Method

All loading and washing of shelves apply. Dont fire shelves with glaze on them
Refer to programing card for how to fire the kiln
Remember the segments include a
“Temp to hit”
How many degrees per hour
How long to hold at “temp to hit”
The “ramp” of “How many degrees per hour” is a “maximum rate” not a minimum rate so
it could go slower but never faster
Fill out the log

Unloading

Put all the shelves and stilts back in their shelves/holding location
Note any problems on the log or put “no issues” on the log
